调查的6074只屈光不正眼,其中远视多于近视(1.378:1),散光多于单纯远、近视;在460只正常视力眼中,仅有55眼(11.96%)光学组合基本正常,余均为异态光学组合;在作屈光系列检查的441只屈光不正者眼中,眼轴、曲率循规者294眼(66.66%)。眼轴与曲率单项反规者125眼(28.35%)。眼轴与曲率均为反规者22只眼(4.99%)。根据其异态光学组合而分别命名为曲轴性远、近视,掺合性远、近视与变异性远、近视。以便在手术矫正中,作术式选择。角膜巩膜缘条带切除,角巩膜缘条带切除缀合术,用以矫正程度不同的远视眼;角膜缘半环或全周条带切除褶(缝)合术,用以矫正各类近视。术式可单独或联合使用,并以切除阈的宽度和长度控制矫正屈光度的大小。以切除子午线的方位,控制,矫正散光的基本原则是切除阈的中央经线,与散光轴垂直。在301例屈光不正的各种手术中,术后6~30个月复查,眼轴、曲率均有少量改善。而手术前后视力与屈光度的改善,有效率为97.68%。经统计学处理(pairing 法)两者均为 P<0.001,有极显著差异;在赤道部巩膜全周板层条带切除,角膜巩膜缘全周条带切除两组动物实验中,组织切片证实眼球前节各组织,不因该两种环形条带切除而有病变出现,与临床使用情况相符。
Among the 6074 normal vision eyes, only 55 eyes (11.96%) had normal optical comparisons, and the remaining Yu mean For the heterosexual optical combination; in the refractive error of 441 refractive eyes, 294 eyes (66.66%) had axial length and curvature. 125 eyes (28.35%) with single axial obstruction and curvature. Axis and curvature were anti-regulatory 22 eyes (4.99%). According to their heterosexual optical combination were named as far crankshaft, myopia, blending far, myopia and variability far, myopia. In order to surgery, for surgical options. Corneal scleral limbic band excision, the limbal strip excision and conjugation, to correct the degree of different hyperopia; corneal limbus half ring or whole week banding fold (seam) surgery, to correct all kinds of myopia. Procedures can be used alone or in combination, and the width and length of the resection threshold to control the size of the refractive correction. In order to remove the meridian direction, the basic principle of control and correction of astigmatism is to remove the central warp of the threshold perpendicular to the axis of astigmatism. In 301 cases of various refractive surgery, 6 to 30 months after the review, axial, curvature, a small amount of improvement. The improvement of visual acuity and refraction before and after surgery, the effective rate was 97.68%. The statistical analysis (pairing method) showed that there was a significant difference between the two groups (P <0.001). In the scleral whole scleral strip removal and corneal scleral margin banding in the equator, Organizations in the anterior segment of the eye did not show any pathological changes due to the excision of the two circular bands and were consistent with clinical use.
